Overview
JFL JFL-B60S curved small hole glossmeter is a common curved glossmeter with a 3 * 6mm small hole measurement diameter. The instrument is suitable for surface Glossiness measurement such as medium Gloss coatings, especially for measurement of curved surfaces or complex shapes, and can achieve small area accurate measurement. The measurement projection angle is 60 °.
Features
1. Equipped with 3 * 6mm small hole measurement diameter, suitable for small area measurement
2. Designed for curved and complex surfaces
3. Measurement Angles at 60 °
4. Use elliptical measurement port shape
5. Operating language is Chinese
6. Portable design, weight only 300g
7. Powered by 1 AA battery
Principle
The glossmeter projects rays of light through the 60 ° Measurement Angles to the measured surface, receives the reflected light and calculates the Glossiness value. The instrument is designed with a small hole measurement aperture, which can accurately measure the Glossiness of curved and complex surfaces.
Applications
Glossiness value of pen body curved surface such as pen, ballpoint pen, automobile coating surface, plastic, decoration, specimen and other surfaces with complex shapes
Standards
ISO-2813、ASTMD2457、GB9754、GB9966、GB8807
Steps
1. Press the switch, place the instrument on the Black Glass standard board, and swirl/spin the adjustment knob to make the displayed value the same as the standard board nominal value
2. Place the instrument on the white ceramic standard plate, and check that the error between the displayed value and the nominal value of the standard plate should not be greater than +/- 1.2 Gloss unit
3. When the error exceeds the difference, it should be re-calibrated
4. After calibrating, the sample can be measured. When the Measured value exceeds 199.9 Gloss unit, the overflow "1" will be displayed.
Notice
• Make sure the standard board is clean and pollution-free before calibrating
• When measuring, the measurement port should be tightly fitted to the measured surface
• Measured value out of range when overflow "1" is displayed
• Regularly check the battery level to ensure normal measurement
• The standard board should be properly kept after use
